How much will it cost to build a prefab in Mississippi?
Many owners budget about $120–$170 per sq ft for prefab construction in Mississippi (home-only), with totals varying by finishes, site work, and location. Metro areas like Jackson, Gulfport, and Biloxi can add permitting and utility costs; rural areas may require added expenses for septic systems, well drilling, site preparation, and coastal areas near the Gulf may need hurricane-resistant features and elevated foundations.

Zoning & Permits
Mississippi operates under home rule with local building code adoption. Jurisdictions that adopt codes typically use the 2018, 2015, or 2012 International Residential Code. The UpCodes Mississippi Building Codes resource provides comprehensive information. Counties and municipalities may opt out of permitting requirements, so verify directly with your local building department for specific requirements.
Off-Grid & Rural Builds
For rural builds not connected to municipal sewer, individual onsite wastewater systems are regulated by the Mississippi State Department of Health Division of On-Site Wastewater. Permits require soil and site evaluations by county environmentalists, and systems must be installed by certified installers. Apply online or through your local health department for permitting and site assessments.
Energy Code & Efficiency
Mississippi references the 2021 International Energy Conservation Code at the state level. Local jurisdictions may adopt and enforce energy codes independently. The Building Energy Codes Program Mississippi provides information on state code adoption. For state-owned buildings, ASHRAE 90.1-2010 applies. Contact your local building department for specific energy code requirements in your jurisdiction.
Local Zoning Tools
Zoning in Mississippi is administered locally by counties and municipalities under the state's home rule framework. The Building Codes Assistance Project Mississippi provides information on local code adoption. Contact your county or municipal building department for site-specific dimensional requirements, setback distances, and use regulations for your property, especially in coastal areas with hurricane wind zone requirements.
Tip
If you're unsure about your parcel's status—whether it requires septic permit approval, falls under local building code jurisdiction, or needs coastal wind-resistant design—contact your local building department or county health department directly. In Mississippi, counties like Hinds, Harrison, and DeSoto all have different local requirements. The resources above are a great place to start.
